Description
- This patent application claims priority to U.S. Provisional Patent Application No. 63/304,491 filed Jan. 28, 2022, which is hereby incorporated herein by reference in its entirety.
- A connector, which includes a
header connector 1 and aplug connector 3, is as shown in U.S. Pat. No. 10,141,669 (and inFIGS. 1A, 1B, 1C, and 1D ), and are to be mated with each other. At the mating end 5 (seeFIG. 1C ) of theplug connector 3 are tab terminals 7 (seeFIGS. 1C and 1D ), each of thetab terminals 7 having a leading edge to be mated with aheader terminal 10 of theheader connector 1 when mated to theplug connector 3. Theheader terminal 10 of theheader connector 1 is connected to acomponent 13. Theheader terminal 10 can be seen through the mating end 18 (seeFIG. 1B ) of theheader connector 1. - As more clearly seen in
FIG. 1D , theheader terminal 10 of theheader connector 1 is in the form of a plurality of contact members that are arranged side-by-side in a stacked arrangement. Each of the contact members has a fork contact at a mating end thereof, each of the contact members having a pair of beams defining a socket (see U.S. Pat. No. 10,141,669) for accommodating therein a corresponding one of thetab terminals 7 of theplug connector 3. Each of thetab terminals 7 of theplug connector 3, which is attached to theheader terminal 10 of theheader connector 1, is connected to a wire or acable 8, which is in turn connected to acomponent 11. - As further illustrated in
FIG. 2A , thetab terminals 7 of theplug connector 3 mates with corresponding ones of the contact members that make up theheader terminal 10 of theheader connector 1; and, as described above, the contact members of theheader terminal 10 are arranged side-by-side in a stacked arrangement. In addition to the contact members of theheader terminal 10, inFIG. 2A , being arranged side-by-side in a stacked arrangement, a double interface is required in the conventional power connector system illustrated inFIG. 2A ; i.e., theconventional header terminal 10 receives thetab terminal 7 of theconventional plug connector 3 at one end, and anothertab terminal 9 of theconventional header connector 1 at the other end. As shown, for example, inFIGS. 2B and 2C , to achieve a right-angle type connection, it is required that theconventional header terminal 10 must receive thetab terminal 7 of the conventional right-angletype plug connector 3 and thetab terminal 9 of the conventional header connector 1 (i.e., a double interface connection). Furthermore, in the conventional power connector system shown inFIG. 2A , three separate components are needed, which increases electrical resistance in the conventional power connector system shown inFIGS. 1A-1D and 2A-2C . - The double interface connection and the requirement of three separate components are similarly needed in the conventional power connector system, as shown in
FIGS. 2D and 2E . InFIG. 2D , theconventional header terminal 10 receives thetab terminal 7 from the conventional right-angletype plug connector 3 and further receives thetab terminal 9 from theconventional header connector 1. InFIG. 2E , theconventional header terminal 10 receives thetab terminal 7 from the conventional straighttype plug connector 3 and further receives thetab terminal 9 from theconventional header connector 1. In either case, as inFIGS. 213 and 2C , the conventional power connector systems inFIGS. 2D and 2E require a double interface for its conventionalconventional header terminal 10 and requires three separate components for itsconventional header terminal 10 to receive, at one end thereof, thetab terminal 7 of a right-angle type plug connector or a straight type plug connector, and thestraight type terminal 9 at an opposing end thereof. The above-discussed increased in parts or elements used in the above-described conventional power connector system, illustrated inFIGS. 1A-1D and 2A-2E , disadvantageously increases the resistance of the conventional power connector system. -
FIGS. 3A and 3B illustrate another kind of conventional power connector system, wherein the header connecter has instead amale tab terminal 20, while the plug connector includes instead afemale terminal male tab terminal 20 of the header connector. Here, the female terminal 25 (seeFIG. 3A ) of the right-angle type plug connector and the female terminal 35 (seeFIG. 3B ) of the straight type plug connector are structurally different, thereby requiring multiple types offemale terminals FIG. 3A , thefemale terminal 25 hasouter holding members 27 andinner holding members 28. In the right-angle type plug connector, theouter holding members 27 are different, in structure or in number, from theinner holding members 28, as shown inFIG. 3A . Moreover, in the straight type plug connector, thefemale terminal 35 haveouter holding members 37 andinner holding members 38. In the straight type plug connector, theouter holding members 37 similarly differ, in structure or in number, from theinner holding members 38, as shown inFIG. 3B . - In view of the above-discussed disadvantages or drawbacks in the structural arrangements of the conventional power connector systems, it is thus necessary to have a power connector system that allows for a single interface, unlike in the power connector system described in U.S. Pat. No. 10,141,669 (and in
FIGS. 1A, 1B, 1C, and 1D ) and the conventional power connector system described above with respect toFIGS. 3A and 3B where a double interface and multiple parts or elements are disadvantageously necessary to achieve their respective functions. - Also, it is necessary for the power connector system to have the same terminal in the plug connector to be used in both a right-angle type plug connector and in a straight type plug connector. That is, it is essential that the header connector be able to mate with the long edge or length side of the rectangular tab terminal (in a right-angle type plug connector) or with the short edge or width side of the rectangular tab terminal (in a straight type plug connector).
- Furthermore, it is necessary to have a power connector system with two assembled components, not the three assembled components found in the conventional power connector systems, such as that shown in U.S. Pat. No. 10,141,669 (see also
FIGS. 2A through 2E ), and inFIGS. 3A and 3B . More particularly, the conventional power connector system, schematically shown inFIGS. 2B through 2E , requires a double interface (that is, the requirement of top and bottom portions of the female receiving terminal), as well as the requirement of at least three separate parts, to achieve a right-angle type or a straight type connection with its header and plug connectors. - A power connector system, which comprises a header connector (header device or the like), which can receive a right-angle type plug connector or a straight type plug connector. The right-angle plug connector is preferably a plug connector having a mating direction, which is 90 degrees from the centerline of a cable exiting from the plug connector. The straight type plug connector is a plug connector having a mating direction, which is parallel to the centerline of the cable exiting the back of the plug connector.
- In a typical header connector, the typical header connector normally holds the male tab terminals. In this invention, however, the header connector holds a female receiving terminal or receptacle made of a high electrical conductivity material. The female receiving terminal or receptacle of this invention includes a plurality of fingers that extend parallel to and spaced apart from each other. The plurality of fingers extend from a joint member, and further provides a structural arrangement that acts as a reinforcement spring. Further, each of the fingers includes an independent reinforcement spring.
- In a typical plug connector, the typical plug connector normally holds a female terminal. In this invention, however, the plug connector holds a male rectangular tab terminal, the male rectangular tab terminal having a short edge (or width side) and a long edge (or length side). Further in this invention, a female receiving terminal held in the header connector can mate with the short edge or width side of the male rectangular tab terminal when the header connector mates with a straight type plug connector. The female receiving terminal held in the header connector can mate with the long edge or length side of the male rectangular tab terminal when the header connector mates with a right-angle type plug connector. The other end of the male rectangular tab terminal includes a wire or a cable attached thereto via welding, mechanical crimp, or the like.
